Linux eth0 incative

Hi there,

I got a problem with my linux eth0.

It worked well, just one day when i boot it, "Failed" to be active.

The eth0 is inactive! I tried to use KDE network configuration tool to add the type of the eth card, I can't make it active. It gave me warning of "the eth card can't be active" (or similar). I tried to "delete" eth0 and "add" a new one, also not working.

In /etc/modules.conf, there is a entry :
alias eth0 eppro (it is just like before when it worked)

i typed:
# ifconfig

it only gave me the lo loopback,

i tried :
# ifconfig etho [up]
it won't work because eth0 is not active.

How can it make it active???

did i choose the wrong type in the list? but it was the same one it worked before.

hope someone give me some help.
Thanks

Is youe eth0 built into the kernel or as a module? If its a module type lsmod and see if it is running. If its not there try to modprobe it and see waht happens.
